A 17' ORNE Y Patented July 11, 1933 FFICE JAY E. WHITE, OF DETROIT, IWICHIGAN, ASSIGNOR TO CHRYSLER CORPORATION, OF DETROIT, MICHIGAN, A CORPORATIGH OF DELAWARE RADIO COIl'TR-OL APPARATUS Application filed October 1, 1930. Serial No. 435,801.

This invention relates to control apparatus for radio receiving instruments.

' The main objects of this invention are to provide control apparatus of this kind having a single operating member by which various elements of the instruments may be selectively regulated either independently or simultaneously; to provide a variable control member which is adapted for installation on the instrument board of a vehicle; to provide means for adjus'tably conditioning radio instrument control apparatus for installation in vehicles having instrument boards of various constructions and inclinations which are located at diverse distances from the receiving set; and to provide means of this kind which will open and close a tube circuit switch.

An illustrative embodiment of the invenfafl 'tion is shown in the accompanying drawing,

in which:

Fig. 1 is a vertical section of a radio receiving set showing control apparatus which embodies my invention.

Fig. 2 is a section taken on line 2-2 of Fig. 1.

Fig. 4.- is a horizontal section taken on line 44 of Fig. 1.

Fig. 5 is a horizontal section taken on line 5 5 ofFig. 1.

Fig. 6 is a fragmentary vertical section of a vehicle body illustrating the manner in 33 .which a radio receiving set having my im proved control apparatus is installed.

In the form shown, a radio receiving unit including a casing, 1 is supported on a bracket 2 which is secured to a dash 3 of a vehicle and located directly above the toe board 4 thereof. The casing 1 has a front wall 5 which faces rearwardly with respect to the vehicle. Mounted on the wall 5 is a tuning instrument 6 such as a variable condenser or variometer including a rotatable part 7 which is carried by a shaft 8. A rheostat 9 or other volume regulating means is provided for varying the intensity of the audible reception. The bulb circuit 11 includes, a switch 59 having a resilient contact member 12 and a cooperating contact member 13 secured to the inner end of the core of the rheostat 9 by a screw 14;. These contact members are separated by an insulating member 15. The contact member 13 has a forwardly extending flange 16 on its upper end which normally abuts the side of the contact member 12 which extends above the flange 16 as shown in Fig. 1. The lower end of the contact part 12 is electrically connected with the conductor 17 of the rheostat. The bulb circuit may be broken by deflecting the upper end of the contact member 12 to the left as viewed in Fig. 1, until it is disengaged from the fl. nge 16 of the contact member 13. The rheostat and switch are carried by a bracket 18 having a vertical arm 19 which is held in spaced relation to the front wall 5 of the casing by a U-shaped spacing member 20. A horizontal arm 21 on the bracket 18 extends inwardly directly over the rheostat 9 and is provided with a pivotally mounted lever arm 22 which contacts with the successive convolutions of the conductor 17. This lever is pivoted at 23 upon a collar 24 which is journaled on a threaded sleeve 25. The sleeve 25 is threaded on the inner end portion 26 of a shiftably mounted rotatable bar 27 which extends through registering apertures in the front wall 5, vertical arm 19 of the bracket 18 and in the sides of the U- shaped spacing member 20. A look nut 28 is provided for adjustably securing the threaded sleeve 25 in a selected position.

The outer end portion of the bar 27 which is received in the above registering apertures has a square cross section on which a pinion 29 is shittably mounted. The pinion 29 is located between the sides of the spacing memher 20 by which it is held in a substantially fixed position while the bar 27 is permitted to be moved inwardly and outwardly with respect to the casing. The pinion 29 meshes with 'a pinion 30 located between the front wall 5 of the casing and the vertical arm 19 95 of the bracket 18. This pinion has a hub part 31 on which pins 32 and 33 are formed. The pins 32 and 33 are journaled in apertures formed in the front wall of the casing and in the vertical arm 19 of the bracket 100 tcctii'ciy. and the pinion 3O meshes with gear 34 which is secured to the shaft 8 of the rot-table part 7 of the variable con- -'.lenser 6.

i h this construction, rotation of the bar 27 2 pinion 29 thereon rotates the pinion 30 and the gear 34 thereby regulatmg the rotat- .at apted deflectthe latter to the left, as in Fig. 1, when the bar is moved to its t position thus opening the bulb cir- Upon rightward movement of engagement with the contact the latter springs back into en L with the flange 16 01'' the Contact 13 thereby closing the circuit. outer end of the bar 27 is flexibly con co. with a control member 37 by a unial joint which includes three pivotally onnected members 38, 39 and 40. The member l a to gue 41 which is received in a 5 4:2 to rmed in the outer end of the bar 27 .e tongue 41 is journaled on a pin 43 extending through the bar 27. Another var:

tongue 4.4 on the member 38 is located in a plan-e which 1S normal to the plane of the t ngue 41 thereof and is received in a groove of the member 39, the members 38 and 39 bei.ng pivotally connected together by a pin i6. Formed on the right end of the member a tongue 47 which is received in a groove 48 of the member 40 and pivot-ally secured thereto by a pin. 49. Thezrightend of the member 10. has a groove 50 in which a tongue 51 on the extremity of the control member 37 is located, the control member 37 and the member 40 of the universal joint being pivotallv connected together by a pin 52.

The control member 37 has a square cross section and it extends through an aperture in an instr inent board 53 of the vehicle in which it is slidably and rotatably supported. Mounted on the inner side of the instrument board 53 is a hracket- 54 having a U-shaped lower, extremity 55. A pinion 56 is located between the sides of the U-shaped end 55 of the bracket 54 and it has an aperture of rectangular shape in which the control member 3'? is slidably received. The pinion 56 meshes with a gear 57 journaled at 58 on the instrument board 53. This gear prefer ably comprises translucent material and it is provided on its face with graduations, not shown, which may be viewed through a sight opening 59 formed in the instrument board.

A bulb socket 60 having a bulb 61 therein is c: rried by a bracket 62 which is mounted on the outer side of the front wall 5 of the casing by bolts 63 which extend through the front wall 5 of the casing and form supports for the U-shaped bracket 20 and the bracket 18 by which the rheostat and condenser control apparatus is supported. The bnlb 61 registers with the sight opening 59 in the instrument board 53 and projects light through the translucent material of the gear 57 thereby rendering the graduations on the gear conspicuous. This apparatus provides indicating means by which the setting of the rotatable part 7 of the variable condenser is disclosed. i

In operation, the control member--37 may be conveniently manipulated by gripping the knob 65'.- thereon so as to either independently shift the bar 27- inwardly or outwardly or to independently rotate the bar. If desired, rotation and translation of the bar 2'? may be effected simultaneously. During rotation of the bar the variable. condenser is regulated and during shifting of thebar the rheostat is regulated. The switch of the bulb strument boards located at various inclina-l tions and by adjust'ably positioning the" threaded sleeve 25 on the bar 27 the control apparatus may be. conditioned for installation in vehicles in which the instrument board is located at diverse distanccsfrom the dash board thereof. This adjustmentmay readily be accomplished by loosening the lock nut'28 and rotating the shaft 27 while holdingthe,

threaded sleeve 25 against rotation thereby and moving the latter either to the right or to the left as viewed in Fig. 1 as desired. The above adjustable control apparatus may be advantageously used in cabinet type radios of the kind generally used in homes in which an instrument panel is employed inplacei of the vehicle instrument board shown. By employing a single control: 'for regulating the rheosta-t and the tuning member and also for operating the bulbcircuit switch, operation of the control apparatus. is. mate.

rially simplified so as to adapt it particularly for installation in a vehicle where the use of even a limited number of radio control gadgets is excessive.

Although but one-specific scribed, it will be understood that various mbodimentof' this inventionhas herein been shown and 1 changes including the size, shape and arrangement of parts may-be made without departing from the spirit of my invention and it is not my intention to limit its scope other than by the terms'of the appended claims.
